Cats do this because its a hunting instinct to snap the neck of their prey.
*the more you know*
those are the eyes of a cold blooded killer
and suddenly everything strange about my cat’s behaviour becomes startlingly clear.
More like disemboweling/tear apart/just break now damn you- cat prey is usually about the size of that ball.
When I play games with my cat it usually winds up with him trying to disembowel my arm.
He’s just a big softy really.
